The cushions to the actual seat are making noise with every movement I do. It's not a spring, screw, bolt,it's the actual cushion. Is there any lubrication I can apply to the seats? I don't want to stuff them with cloth or get all new chairs. Ive tried steam cleaning, wd-40, I'm irritated especially with the driver seat. It's only gets worse.. hoping someone would know of a product that would eliminate the noise.
